Cleveland Cavaliers star LeBron James, who at 22 already has endorsement contracts worth an estimated $150 million, will make cameo appearances on national TV commercials for the new Windows Vista operating system. Spots for the consumer version of the software will begin airing Jan. 30.

James is the first NBA player that Microsoft has used to promote its products--but Vista may not be the last Microsoft project for the basketball star. "We're talking about what future projects we might do with him," says Microsoft spokesman Lou Gellos.

James and Microsoft previously worked together during the player's summer bicycle event for charity in his hometown of Akron, Ohio.

Microsoft declined to reveal how much it paid James, who signed a three-year, $60 million contract extension with the Cavaliers last July. In an interview last year, James said one of his primary goals is to "be the richest man in the world."
